Perseus RESTful API Client Python Library
Project description
Perseus RESTful API Client Python Library
Repository of classes that provide Pythonic interfaces to connect to a RESTful API server developed with Perseus RESTful API server framework.
Python Library Poster 0.8.1
Note: this library includes a modified version of poster 0.8.1
, which original version provides a set of classes and functions to facilitate making HTTP POST (or PUT) requests using the standard multipart/form-data encoding.
The original library poster 0.8.1
cannot be used to upload file uploaded into memory (i.e., stream-to-memory), like for instance django InMemoryUploadedFile
. The reason is that such file-like object doesn't support the method fileno()
used by the poster 0.8.1
to determine the size of the file-like object to upload in Python module poster.encode
:
if fileobj is not None and filesize is None:
# Try and determine the file size
try:
self.filesize = os.fstat(fileobj.fileno()).st_size
except (OSError, AttributeError):
try:
fileobj.seek(0, 2)
self.filesize = fileobj.tell()
fileobj.seek(0)
except:
raise ValueError("Could not determine filesize")
This code raises the exception io.UnsupportedOperation
that poster 0.8.1
doesn't catch. Chris AtLee included Alon Hammerman's patch in the tag tip
of the library ``poster, for catching the
io.UnsupportedOperation for fileno` on 2013-03-12:
try:
from io import UnsupportedOperation
except ImportError:
UnsupportedOperation = None
(...)
if fileobj is not None and filesize is None:
# Try and determine the file size
try:
self.filesize = os.fstat(fileobj.fileno()).st_size
except (OSError, AttributeError, UnsupportedOperation):
try:
fileobj.seek(0, 2)
self.filesize = fileobj.tell()
fileobj.seek(0)
except:
raise ValueError("Could not determine filesize")
However, the latest version of poster
installable with pip
is still 0.8.1
.
